If you miss someone who does not miss you, is not good for you, or is unattainable… Take all of the love you once felt for them and spread it around other places. Give your love in worthwhile people and things. Turn the romance into passions for hobbies or admiration for others - enrich your own life. Focus on yourself and those who actively make you happy.
Even though I complain sometimes, it’s because I’m the heart of a person, and people’s hearts are that way. People are afraid to pursue their most important dreams, because they feel that they don’t deserve them, or that they’ll be unable to achieve them. We, their hearts, become fearful just thinking of loved ones who go away forever, or of moments that could have been good but weren’t, or of treasured that might have been found but were forever hidden in the sands. Because, when these things happen, we suffer terribly.
Happy is the man who has broken the chains which hurt the mind, and has given up worrying once and for all. Be patient and tough; one day this pain will be useful to you.
That’s the problem with putting others first; you’ve taught them you come second.
